Hi I'm using int osc in 16f628a. I want to use A6 for led (output).
Physically my circuit is ok. When I powered up, my led light right away. If I do reset, MCLR led goes off. When unpress mclr, goes on and stays on all time. I tried two 16F628a - same problem. I tried output_low(LED1) in my program...same thing. Do I have to define A6 as output?
Thanks for help..again... ![Exclamation](images/smiles/icon_exclaim.gif) |

Please show us your 'fuses' line.....
Hint...
In order to use A6 as an I/O pin it must be configured using the fuses options... |
